SRX2/SRX3 Battery Warm-Up Time

If a battery has been used in an extreme hot or extreme cold environment, charging does not start immediately.

When the battery is placed in the charger, the battery port LED indicator turns yellow. Charging only begins after the battery reaches the proper temperature range - 32 °F (0 °C) to 104 °F (40 °C). It may take up to 30 minutes for the battery to reach a safe temperature.

If battery temperature does not come into range in about one hour, the red LED blinks indicating that there is a charger fault.
